A friend of mine has a C5 and has been having a problem. When he turns the A/C on, the passenger side blows cold air and the driver side is still hot air. Are these vents vacuum operated or are they
When you turn on the A/C on a friend's C5, the drivers side vent blows hot air and the passenger side blows cold. Are the vents vacuum operated or gear/motor driven?? Has anyone out there experienced and repaired this problem??
